Answer: Decrease his inputs
Explanation: Chuck has decided to decrease his inputs using the terminology of equity theory. The equity theory is based upon the fact that individuals or employees are motivated by fairness and calls for a fair balance to be struck between an employee's inputs and outputs which ultimately ensures strong and productive relationships with employees who are both contented and motivated. Employee equity is measured by comparing the ratio of contributions or costs and benefits or rewards for each employee. Chuck spending an extra hour at lunch every day is the loss of an hour's work (input).
